I do a cold backup of my repository daily.
Replication of it is not a bad idea, as Arup mentioned,
though I haven't tried it myself.
Speaking of backing up the RMAN repository, does anyone
back them up hot?
Seems to me that would not be a good idea.

The earlly versions of rman suggested that you put a 2nd recovery catalog
in one of the databases you are using the "real" recovery catalog for.
Then
you use this to record the backups of the recovery catalog database. I
never headed this advice, altho I do use a recovery catalog for all
production, developement, and test databases that I back up.

Yeah but do you have to pay for another Veritas NetBackup license and
server to backup the catalog? If just have one database server and one
database license why should I have to buy another license and install
another 1-2GB of Oracle software on another server? The only answer I can
think of is so Larry can spend more money on yachts, planes, and cars.
Contrary to Oracle Corporate aspirations, not all data in the universe
really needs to be stored in Oracle databases, especially backup
information
about Oracle databases I want to backup. If I need a database to backup a
database then do I need another database to backup the database that
backed
up the original database? ;-) Seems the simple solution to this silliness
is
just to remove the requirement of having a database to backup a database.

Why silly?
It isn't any more silly than making a separate backup of the Veritas
Netbackup catalog.
It's just a different level of abstraction.

If you aren't using a repository all you have to do is make sure control
file backups are part of the routine. There are 2 ways to backup the
backup metadata: 1) the RMAN repository database; 2) backup
controlfiles.
Functionally and operationally they're pretty much the same. The only
things you can't do with controlfile RMAN/database metadata is: 1) use
previous "incarnations" of the database for recovery; 2) use database
stored scripts. No big deal as far as I'm concerned.
When RMAN first came out a separate repository database was a
requirement.
Subsequent releases added some functionality for using controlfiles. The
vulnerability of losing the repository or losing the backup controlfile
is
about equivalent. The overhead of the repository database is more. With
the initial releases of RMAN (EBU) Oracle was rightly criticized for the
fact that you had to backup the database that holds information about
the
database you want to backup. Getting rid of this silliness seems
reasonable to me.

And how does one go about restoring a database when all control files
are lost, and the only recovery data is stored in the control file?
This doesn't sound very reasonable.

Joe,
That's what I have heard (from 2 Oracle University
Professors/Lecturers/Demonstrators). But no one would tell me when it
may
happen. We do not use RMAN (yet) so I did not pursue it further.

Obilgatory oracle statement/question: rumor has it by some instructors
that RMAN repository is going away and only control file recoveries
will be possible, truth or fiction?
